Start with the public source.
Prices come from each panel’s public /services page. The crawler does not log in or place orders. An owner-provided, read-only API is used only after an administrator stores a key, encrypted at rest.
Collections observe published prices. We do not test service quality or guarantee delivery. Always review the panel’s current terms.
One panel, one catalog.
A domain becomes active after DNS resolves to a public address, HTTPS responds, a Perfect Panel fingerprint is detected, and at least one service parses. Other states include candidate, unreachable, dead, and mirror.
Domains with the same catalog hash are treated as one panel and a mirror. Scheduled collection respects crawler rules, uses delays, and backs off after failures.
A shared unit. An explicit classification.
Rates use USD per 1,000 units, stored as integer micro-USD. One dollar is 1,000,000 micro-USD. Order totals use the requested quantity and the same integer rate.
Original categories are preserved. A separate taxonomy maps service names to platform, category, and subtype. Names below the confidence threshold wait for review and remain outside comparison tables. Full catalog search includes unclassified names.
Recent evidence comes first.
By default, a category or subtype becomes indexable with at least five eligible offers from three panels and a price observed within 72 hours. Administrators can configure these thresholds.
Filtered views retain quantity, refill, location, and target in their canonical URL and are not indexed. Samples are labeled and excluded from live index eligibility. Only eligible pages enter the sitemap.
Paid placements are always visible.
Sponsored modules are labeled and use sponsored links. They do not change the order of organic comparison rows. We do not invent star ratings, quality rankings, or delivery scores.
